Question

Tìm x: 
a, 3,72 x ( x- 1,03 ) = 13,02
b, ( x- 2,48 ) x 2,45 = 21,07
c, ( 60 - x ) : 3,15 = 12,23
d, 22,1: ( 8,3- x ) = 3,4
giúp mình trước 2h30 nhé!

Answer 1

a) \(3,72\left(x-1,03\right)=13,02\)

\(3,72x-3,8316=13,02\)

\(3,72x=16,85\)

\(x=4,53\)

Answer 2

b) \(2,45\left(x-2,48\right)=21,07\)

\(2,45x-6,076=21,07\)

\(2,45x=27,146\)

\(x=11,08\)

Answer 3

c) \(\left(60-x\right):3,15=12,23\)

\(60-x=38,5245\)

\(x=21,4755\)

d) \(22,1:\left(8,3-x\right)=3,4\)

\(8,3-x=6,5\)

\(x=1,8\)
